You can split long reinforcing bars and bar groups that exceed the stock length, and create splices in split locations.
Use the Automatic splicing
tool macro to split and splice reinforcement that exceeds the stock
length. You can first check the length of the reinforcing bars in the model
according to the manufacturer. You can then define the portion of the reinforcement
to be split and spliced in the same cross section, and the location, symmetry, type,
and length of the splices.
Note:
Automatic splicing tool does not work with rebar sets. To split bars in rebar sets, use splitters instead.
If the reinforcement that is going to be split
belongs to a rebar assembly, the newly split bars are also added to the
rebar assembly.

Click
the Applications & components button in the side pane to open the
Applications & components catalog.
-
Click the arrow
next to Applications to open the applications list.
-
Double-click
Automatic splicing tool to start the macro.
-
In the
Automatic Splicing Tool dialog box:
-
Select the manufacturer of the reinforcement.
The maximum bar lengths and lap lengths are then listed by the grade and size of the bar.
If needed, you can define the length information in the
AutomaticSplicingTool_Manufacturers.dat file. You can copy the default file from
..\ProgramData\Trimble\Tekla
Structures\<version>\environments\common\system
, edit it, and save it to your project or firm folder.
-
For the bar grades and sizes that are not listed in the
AutomaticSplicingTool_Manufacturers.dat file, use the
Maximum length for unspecified stock box to define the maximum reinforcing bar length after which the bars are split and spliced.
-
To check if the length
of the reinforcing bars exceeds the maximum length, use one of the
buttons next to Perform check to:
-
To check all
reinforcement in the model, click
All.
-
To check specific reinforcement, first
select the reinforcement or cast units in the model, and
then click Selected.
Tekla Structures lists the reinforcing bars that are longer than the maximum
length under Longer rebars on the right side
of the dialog box.
When you select a row
in the Longer rebars list, Tekla Structures highlights the corresponding reinforcement in the model.
-
Define which proportion of the reinforcement can be spliced in the same cross section.
-
Define the symmetry that
is applied when the reinforcing bars are spliced.
-
Define the offset of the
splice center point.
-
Define the minimum
longitudinal distance between two parallel bar splices.
-
Select the splice type.
You can create lap splices, coupler splices, or welded splices.
-
For lap splices, define
the default lap length as a distance or in relation to the nominal bar
diameter.
This value will be
used if there is no lap length defined for a bar grade and size in
the AutomaticSplicingTool_Manufacturers.dat
file.
-
For lap slices, define whether the lapping bars are on top of each other or parallel to each other.
-
To split and splice
reinforcement, use one of the buttons next to Perform split
and splice to:
-
To splice all
reinforcement in the model, click
All.
-
To splice
specific reinforcement, first select the reinforcement in
the Longer rebars list, or in the
model using the Select objects in
components switch , and then
click Selected.
